The combustion air is three fold:
Primary air (1), secondary air (2), third air (3).
Primary air (1), secondary air (2), tertiary air (3).
Each of these air flows is led across its own inlet and
internal distribution channels to its respective place
of task. Regulation is done with the air control push
rod (4). .
The primary air (1) has as task to steer the
degassing speed.The secondary air (2) is necessary
additional and preheated air that comes directly
on the fuel from above. The secondary air (2) is
preheated and additional necessary, it comes
directly on the fuel from above. This air keeps the
window clean.
The tertiary air (3) is led directly in the hot gas zone
and brings in the oxygen, necessary for a perfect
combustion of the gases.
Illustr.4: air flow control
The air control push rod (4) can be put in three different positions. This way the respective air circulations are
adapted to the combustion situation.
